All textbooks in C and C ++ warn us not to use functions to return struct or class objects. Otherwise, memory replication and calling of the replication constructor may occur, reducing performance. I believe this sentence has become a common sense

"One-time Encoding and multiple use" is the root cause of the introduction of generics. In the past, C ++ was called a template.AlgorithmAnd the data structure support independent encoding. For example, the generic list means that you do not have to
